Research ArticleOpen accessEvery word in the titlePreparation and Polishing Properties of Spherical Porous Silica AbrasiveHong Lei, Hu Li, Ping Liu, Ruling ChenProblem statement: Abrasive is one of key influencing factors on the polished surface quality in Chemical Mechanical Polishing (CMP). Solid abrasives in CMP slurries are easy to cause polishing scratches. It is well known that reducing the hardness of abrasives would improve the polished surface quality. Therefore, the change in structure or shape of the abrasives means a change in … …Current Research in Nanotechnology, Vol. 1, Issue 1 · 15 Jun 2011 · 9,285 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMechanical Strength and Durability Properties of High Performance Mortar Containing Densified Silica FumeCheah Chee Ban, Mahyuddin RamliProblem statement: Numerous data and information on pozzolanic reaction and microfiller properties of silica fume were derived from laboratory investigation on silica fume in undensified form. Currently, due to low bulk density of undensified silica fume which poses problem in transportation and handling of the material, silica fume are commercially supplied in densified form. Densification process used to increase bulk … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 7,956 accessesView PDFCite

Approach: The aim of this research was first, to achieve the best mix design of light weight concrete which could be in light weight concrete category and second, by applying the first part gain the main reason of this research which was finding the … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,620 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleProduction of Silica-refractory Bricks from White SandGazze AlmarahleAt present, no refractories are produced in Jordan, but large quantities are imported for use in the lining of furnaces and kilns in the metallurgical industries.The aim of this study is to initiate a program of research for production of silica-refractory bricks from local materials.The raw material, which has been used in this study was white sand. This sand contains … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 7,332 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHigh Quality Komatsuna (Brassica rapa L. nothovar) Production by Using Silicate Minerals Treated Nutrient SolutionSheheli Islam, Kumagai Kazunori, Noriko Takeda, Katsumi IshikawaProblem statement: Good water quality not only produces good crop yield, but also maintains environmental quality and so with plant, animal and human health. Therefore, protecting the quality of water by using non chemical materials is an emerging issue to be solved. Bakuhan seki having additional negative charge were found to have the capacity of improving condition of water while … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 8,637 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInfluence of Acid Frosting on the Microstructure Characteristics and Mechanical Strength of Eroded Soda-Lime-Silica Glasses by SandstormAkinwumi Gbenga Owoyemi, Grace Olufunke Matthew, Seun Samuel OwoeyeMost glass products such as cars windshields, solar panels protecting glass and windowpanes are exposed to unavoidable sandblasting effects especially in areas prone to sandstorms. This sand impingement results into micro cracks and surface flaws which altered the structure and strength of the exposed glasses thereby lowering their service life. In this regard, attempt was made in this research to … …International Journal of Structural Glass and Advanced Materials Research, Vol. 3, Issue 1 · 25 Apr 2019 · 6,918 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInvestigation of the Characteristics of Thulium Doped Alumina Nanoparticles for Applications in Silica-Based FibersNur Atiqa Bt Rahmat, Hairul Azhar Abd Rashid, H.Y. Wong, Mukter ZamanIt is reported that during the fabrication of doping RE ions into the silica preform, the distribution of particles is inhomogeneous and becomes uneven throughout the fiber which lead to unwanted spectroscopic characteristics. It is assumed that by using thulium doped with alumina, the problem with the inhomogeneity of the particles inside the fiber can be solved. With the incorporation … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 26 Jan 2017 · 7,411 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePhotostability of Ponceau 2R Doped Thin Film Sol-Gel Silica as Luminescent Solar CollectorS.M. RedaProblem statement: Current researches had shown that the photostability of a luminescent solar collector depend on the method of its preparation and type of using dye. This research therefore aimed at studying the stability of luminescent solar collector prepared by sol-gel spin coating method using Ponceau 2R. Approach: The effect of silica matrix on the photostability and fluorescence properties of … …Energy Research Journal, Vol. 1, Issue 1 · 30 Jun 2010 · 7,222 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCohesiveness and Flowability Properties of Silica Gel PowderE.C. Abdullah, A.M. Salam, A.R. AzizProblem statement: The measurement of powder flowability is a major concern for most industrial processes that deal with the handling of bulk solids as raw materials, intermediates, or products. Approach: The influence of particle size on the flowability of silica gel was investigated using aerated and non-aerated methods. The aerated method involved the measurement of the Hausner Ratio (HR) and … …Physics International, Vol. 1, Issue 1 · 31 Mar 2010 · 15,527 accessesView PDFCite
